ERASTUS E. WINKLEY, OF LYNN, MASSACHUSETTS, ASSIGNOR TO UNITED SHOEMACHINERY -CORPORATION, OF PATEBSON, NEW JERSEY, A CORPORATION F NEWJERSEY.

Application filed April 18,

This invention relates to machines for use in the manufacture ofbootsand shoes for performing what is commonly termed the leveling operation,and more particularly to machines of that type in which a shoe supportand a leveling tool, such as a roll, are relatively movable lengthwiseof a shoe on the support to cause the tool to operate progressivelyalong the bottom of the shoe.

lVhile such machines are used principally for shaping the outsoles ofshoes, they are also sometimes used to prepare the bottom of a lastedshoe for the reception of the outsole, and the term leveling isaccordingly i5 employed herein in a general sense to comprehend suchdifferent uses. The invention is herein illustrated in its applicationto a machine organization of the same general type as that disclosed inLetters Patent No. 1,667,7 61, granted on May 1, 1928 upon anapplication of E. E. lVinkley and H. A.

Davenport, and in various Letters Patent therein referred to, althoughit is to be understood that the invention is not thus limi ited in itsapplicability.

Leveling machines of the above-mentioned type have been commonly sodesigned as to confine the actionof the leveling roll substantially tothe forepart and shank portions of the shoe bottom. Shoes, however',frequently require more or less shaping of the heel end portion of thesole, and it has been the general practice to perform this operationmanually, when needed, by the use of a hammer, although it has beenproposed to levelthe heel end of the shoe in the leveling machine by theuse of a supplemental roll, as disclosed in a copending application ofH. A. Davenport, Serial No. 147 ,007, led on November 8, 1926. In orderto level satisfactorily all portions of the heel end of the sole by aleveling roll, it is necessary that the roll in its operation pass tothe rear of the heel end of the shoe; and this involves the necessity ofcontrolling the roll in such manner as to prevent it from distorting theedge of the sole in leaving the shoe or in returning to a position overthe shoe. Y

The present invention, in one important aspect, accordingly provides anVimprovement in means for controlling a leveling'tool or roll in leavingan end of a shoe or in returning to a position over the shoe. The in-SHOE-LEVELING MACHINE.

1928. Serial No. 271,051.

vention is illustrated as applied to an organization including asupplemental roll for operating upon the heel end of the shoe inaccordance with the general disclosure of the above-mentioned Davenportapplication, although it is not limited to an organization o thatparticular character.- For the purposes in view, the construction showncomprises a roll support or receiver which is movable heightwise of theshoe to a position determined by engagement of the supplemental rollwith the heel end of the shoe and is automatically locked against anysubstantial movement in the direction of the pressure applied by theroll from the position thus determined, the locking of the roll supportbeing controlled by the relative movement of the shoe support and therolls lengthwise of the shoe. Accordingly, as the roll which operates onthe heel end of the 'shoe passes to the rear of the heel end,

which resultsk in the construction shown from swinging movement of theshoe Support or jack relatively to the roll, it is supported and heldautomatically against movement below the plane of the heel seat, so thatneither in leaving the shoe nor in its return to a position over thebottom of the shoe is there any danger of damage to the edge of thesole. As herein illustrated, the roll support is carried by the jack andis so mounted and controlled that after it arrives in roll-supportingposition it is stopped and held in that position while the jackcontinues its movement to carry the shoe past the roll. It is a furthercharacteristic of the construction shown that the means for locking theroll support as above described acts also automatically to unlock itimmediately upon the return of the roll to a position over the heel endof the shoe in the reverse movement of the jack, to permit the levelingpressure to be again applied.

In operating upon some kinds of shoes it is desirable to prevent aleveling tool or roll that operates upon the heel end of the shoe fromoperating upon some other portion of the shoe, in order to avoid dangerof possible damage to the shoe or danger ofdistorting by the action ofthe heel end roll the shape produced by another roll. In operating, forexample, upon shoes havinghigharched Shanks, it is desirable to preventthe heel end roll from engagingthe ball portion of the shoe which, inthe leveling machine, is positioned at a height considerably above theheel-seat.Y In view of this and other considerations, the inventionfurther provides novel means for controlling, with respect to movementheightwise of the shoe, a leveling tool or roll which operateson theheel end of the shoe, or, in another aspect, for controlling differentleveling tools or rolls with respect to such movement. As hereinillustrated, there is provided automatic means for controllingthediilerent rolls independently Aof each other, so that the roll whichoperates at thev heel end is moved into and out of engagement with theshoe at different times from the other roll to avoid contact withportions of the shoe upon which it is not desired that it shall operate.

The above and other features of the invention, including also novelmeans for manually controlling the tool support with respect to movementtoward or from the shoe, and various novel details of construction andcombinations of parts, will now be more particularly described byreference to the accompanying drawings and pointed out in the claims.

In the drawings,

` Fig. 1 is a View in side elevation ofa machine in which the inventionis embodied;

F ig. 2 is a perspective view of a portion 'of the machine; and

Figs is a view substantially in side elevation on a larger scale ofportions of the structureshown in Fig. 1, with the parts as they appearat an intermediate stage in the cycle of the machine.

Leveling machines of the type illustrated are twin machines includingtwo sets of operating instrumentalities for operating` respectively 'ondiilerent shoes in different locations in the machine. For the purposeof an understanding of this invention only onel of these sets ofinstrumentalities is shown in the drawings and will be hereinafter' de`'scribed since it will be understood that meehanism such as illustratedwill be substantial.- ly duplicated in the opposite half of the machine,and it is further to be understood that the invention is not limited tomachines of the twin type.

For supporting a shoe a tov receive the leveling pressure the machine isprovided with a shoe support or jack comprising a heel post 10 and a toepost 12 which are relatively adjustable Vabout an axis at la by means ofa hand wheel 16 for shoes of different sizes, the jack as a whole beingmovable about an axis at 18 to carry the shoe forwardly and rearwardlyunder'a leveling tool or roll 2O for applying leveling pressure to theforepart and shank portions of the shoe bottom. The leveling roll 20 ismounted on a holder 22y which is supported on a roll carrier 24 pivotedat 26 on the frame of Vdisclosed in Letters Patent the machine forswinging movements in a vertical plane to pressthe roll upon the shoeand to withdraw it from Vthe shoe at different times in the cycle ofoperations. To cause the roll to operate progressively along the bottomof the shoe the 'jack is swung about its axis 18 by power-operatedmechanism, which it is unnecessary to describe in detail lsince it isfully described in prior Letters Patent including those hereinbeforereferred to. The cycle of operations, which inay be variously modiliedas far as the present invention is concerned, may comprise as heretoforefirst a full forward movement of the jack to cause the roll 2Ol totraverse the shoe bottom from the toe end to the rear end of the shank,then a plurality of short backward and forward vmovements while the rollis operating` at one side of the shank, thereafter long backward andforward movements to cause the roll to return to the toe end along oneside and then to operate from the toe to the rear of the shank along theopposite side, followed by a plurality of short backward and forwardmovements while the roll is operating `at that side of the shankand'iinally a movement to cause the roll to return to the toe. Inthecourse of these operations the roll may be tipped in various ways bymovement of its holder 22, as also fully disclosed in the prior Letterslbatent.V

' At the beginning of the operation of the machine the roll 20 issupported in a position somewhat above the level of the toe end of theshoe, as illustrated in Fig. 1, by yieldlable means including a springplunger 27, as fully disclosed in the Tvllinkley and Davenport patenthereinbefore mentioned. For moving the roll down into engagement f'iththe toe end of the shoe bottom lat the beginning of the cycleofoperations and for releasing it to permit it to be raised by theplunger V27 at the end of the cycle, there is provided a cam wheel 28 ona cam shaft 30, the periphery of this cam wheel being' arranged to acton a lever 32 connected by a link 34 to a lever 36 on the frame of themachine. The lever 86 is arranged to bear upon the upper end of aplunger 38 which acts through a spring 40 on a lever 42 connccted by alink `44C to the roll carrier 2st. Through these connectionsv the roll2O is made to bear yieldingly upon the bottom of the shoe. Asillustrated, the cam wheel 28 is so formed as to adapt it to relieve thepressure of the roll 20 on the shoe at certain times between thebeginning and the end of the cycle; but there is preferably alsovprovided means for rendering it ineffective thus to Vrelieve thepressure in operating on shoes that do not require such pressure relief,as No. 1,685,387, granted on September 25, 1928 upon an application ofE. E. llfinkley and l?. V. Hart.

fl U

The machine herein shown is further provided with an additionallevellingr tool or roll 46 for applying leveling pressure to the heelend of the shoe bottom while the roll 2() is operating upon otherportions, especially the shank. This roll is mounted for turningmovement in a holder 48 having an upwardly extendingr shank 50 mount-edin a roll carrier bracket 52 which is secured to another bracket 54pivoted at 56 on a roll carrier arm or lever 58 pivotally mounted at 60on the frame of the machine. Y The holder 48 can be turned about theaxis of its shank 50 to position the roll 46 at different angleslaterally ot the shoe, and it is secured in adjusted position by meansof a lscrew 62 whereby the shank 50 is clamped in the bracket 52. rIhebracket 52 is secured to the bracket 54 by clamping screws 64 whichextend through slots in the bracket 52, as shown in Fig. 2, to permitthe roll to be adjustably tipped about an axis extending lengthwise ot'the shoe. By movement ot' the bracket 54 about the axis of its pivot 56the roll 46 mayl be positioned at different distances lengthwise ot theshoe from the roll 20, and the bracket 54 is secured in adjustedposition by means of a clamping screw 66 on the arm 58. The means thusfar described tor supporting and adjusting the roll 46 is similar tolwhat is disclosed in the Davenport application v hereinbeforementioned.Y f

For one of the purposes ot the present invention the machine is providedwith novel means for controlling the roll 46 with respect to movementheightwise ofthe shoe into or out of enga-gement with the shoe. It isdesirable that this roll be positioned close enough to the roll 20 sothat it may operate upon the heel end of the shoe while the roll 20 isoperating on the shank portion of the shoe. lVith the two rolls in thatrelation to each other there are times in the cvcle of the machine whenthe roll 46 is located over the orepart ot' the shoe, as illustrated forexample in F ig. l. It is usually preferable, however, that the roll 46be confined in its operation substantially to the heel end ot' the shoe,in order to avoid objectionable results such as might arise from itsengagement with other portions of the shoe. .Automatic means isaccordingly provided for controlling the roll-carrying arm 58 independently of the carrier 24 for the roll 20, so that in the forwardmovement ot the jack the roll 46 is not moved downwardly into engagementwith the shoe until that time in the cycle when it is positionedsubstantially or approximately over the heel end of the shoe, and sothat in the reverse movement of the jack it is lifted out of engagementwith the shoe before the parts are in position for it to act to anysubstantial extent on portions of the shoe .bottom in front of vrollreceiver 1702.

the heel seat. For this purpose the cam shaft- 30 carries a path cam 68whichengages a roll on one end of avlever 7() pivoted at 72 on the frameof the machine, the other end of this lever being connected to a Vrod 74which is slidingly movable through a bushing 7 6 threaded in one end ofa sleeve member 7 8 which is pivotally mounted at 80 on the arm 58. lBetween the bushing 76 and a flange 82 on the rod 74 there is mounted aspring 84 through which pressure is applied yieldingly to the arm 58 bythe lever to force the roll 46 downwardly against the shoe. The rod 74-carries at its outer end nuts 86 for engaging the bushing 7 6 to afl'orda positive connection between the lever 70 and the arm 58 to lift theroll 46 from the shoe. The path cam 68 is so formed as to force the roll46 downwardly upon the shoe when the jack has been moved far enoughforwardly to bring the shoe substantially into position for this roll toact on its heel end portion, and to lift the roll from the shoe at thecorresponding time in the reverse movement of the jack, the rollthusbeing lowered and lifted in each full reciprocation of the jack inthe cycle of the machine.

In order that the roll 46 shall apply its pressure evenly to allportions of the heel end of the shoe bottom, it is desirable that ineach forward movement of the jack the 1 heel end of the shoe shallbecarried beyond this roll. In order, however, to avoid danger of damageto the rear .edge of the sole, it is necessary to prevent the roll inthat movement of the jack from dropping oil' the heel end of the shoeandalso to control it in such manner as to prevent it from delivering ablow on the rear edge of the sole in its ret-urn to a position over theshoe bottom in the reverse movement ofthe jack. The inventionaccordingly further provides novel means for accomplishing this result.For the purpose in view there `is pivotally mounted at 88 on theheel-supporting portion 10 of the jack an arm 90 which carries aroll-supporting device on its upper end. The arm 90 is provided with alug 92 engaged by a spring plunger 94 tending to swing the arm forwardlytoward the heel end of the shoe and for limiting the swinging movementin this direction the arm carries a rubber -pad 96 arranged to engagethe heell end face of the shoe. Slidably mounted in a bore in the arm 90is a rod or plunger 98 fast on the upper `end of which is a bracket 100having mounted thereon a U-shaped roll supporting member or The two armsof this member are arranged to extend forwardly at opposite sides of theheel end of the shoe and are provided withyinclined faces 104 arrangedvto be engaged by diametrically reduced portions `106 at theopposite'ends of the roll 16, and also with hollows or de -ber rand itssupporting bracket downwardly against the resista-nce of the spring asthe jack-is moved forwardly to cause the roll to operate along the heelscat, the reduced portions of the roll entering the depressions 108before the shoe is moved :tar enough to carry'it beyond the roll. Themember 102 is provided with a'spindle 112 mounted in the bracket 100 forturnii'ig movement about an axis extending lengthwise of the shoe, sothat the member 102 can tip laterally to adjust itself to the directionof the axis of the roll 416. For limiting such tipping movement theVspindle 112 is provided with a projection 114A which etc tends into aslot formed in the bracket 100, as shown in Fig. 2. To prevent turningmovement of the roll support about the axis of the plunger 98 thebracket 100 has a pair of downwardly extending arms 116, only one ofwhich is seen in the drawings, these arms being arranged to engage lugs118 projecting laterally from the upper end of the arm 90. To limitadjustably upward movement of the roll supportV in response to theaction of the spring110, one of the arms 116 carries a screw 120 forengaging the lug 118 at that side oi the arm 90. f

It will thus be seen that as the roll 16 operates on the heel endportion of the shoe bottom the roll support, comprising the members 100and 102, is adjusted automatically by the action of the roll to heightdetermined by engagement ofthe roll with the heel end ot' the shoebottom. To rein lder the yroll support effective to prevent anysubstantial. downward movement of the roll below the plane of the heelseat when the roll ispositioned at the rear of the heel end of the shoe,there is further provided means for locking the support against anysubstantial downward movement from the position to which it is adjustedin the manner "above described. F or this purpose the arm 90 is providedwith a series of upwardly directed ratchet teeth 122 and the downwardlyextending arms 116 of the bracket 100 carry apair of pawls or latches1211 pivotally mounted on a rod 126 which eX- tends acrossA from one armto the other. The ends of these pawls are spaced apart vertically -adistance less than the distance between adjacent ratchet teeth for thepurpose of greater precision. Each pawl is provided with a tail portion128, and associated therewith is a pawl controller comvprisinga curvedarm 130 also pivoted on the rod 126 and having on its lower endlaterally extending lugs which carry rods 132 (F ig. 8) projectingupwardly through openings in the tails 128 of the pawls, these rodshai/'ing thereon springs 134 through which the pawls are swung inwardlyagainst the` ratchet teeth in response to swinging movement or' the arm130 toward the lett (Fig. Such movement of the armV 180 is effectedautomatically ata time in the cycle before the roll reaches the rearedge of the heel end of the shoe bottom by the action of a portion ofthe roll-carrying bracket member 5.2 upon a screw 136 adjustably mountedin a holder 138 secured to the upper end of the arm 130. Prior to thattime in the cycle the pawls 1211 are held out of engagement with theratchet teeth by the action ot the arm 130 upon their tail portions 128under the influence ot a spring 139 the opposite ends of which areconnected respectively to the arm 180 and to the member 100. A shoulder140 on the arm 180 is arranged to engage the member 100 to limit itsmovement under the force of the spring 139, as shown in Fig-3.1 and 2. V

t is vdesirable that before a shoe is mounted on the jack the means forsupporting the roll at the heel end shall be swung away from theshoe-supporting portion of the jack, that is, to the left -from theposition that it occupies iirFig. 1, so as not to interfere with thepresentation ot the shoe. For this purpose there is convenientlyutilized mechanism such as provided heretofore for use in jacking theslice, features of which are described and claimed in a. ccpendingapplication of E. E. inkley and H. A. Davenport, Serial No. 12,287, ledon February 28, 1925. This mechanism comprises a pivoted'hand lever 1/12having arms that extend at opposite sides of the heel post 10, as shownin Fig. 2, and con- Vnected by'means fully described in theAabove-menti.onedV application to a bar 141- which acts on a swingingheel-pin carrier 14.6 to tip the shoe in a direction to force its. toeend down uponv a toe rest 1118. It will be understood that such jackingof the shoe is effected by downward movement oic the hand lever, andthat prior to the jacking operation the lever occupies position higherthan that in which it is shown in the drawings. l'n order to utilizethis lever to control the roll support, the arm 90 is provided with aprojection having portions at the opposite sides ci the arm on which areformed inclined lower Faces 152, and the two side arms oi the lever 142are provided with rolls 154 in position to engage these inclined facesant thereby to force the arm 90 rearwardly against the re sistance ofthe spring plunger 9e. lNhen the shoe is jacked by downward movementof'tlielever, the arm 90 is released and is swung toward the shoe by theplunger 94 until the pad 96 engages the end face of the shoe.

In the operation of the machine, a shoe is first mounted on the jack andthe lever 142 isthen moved downwardly by the operator to jack the shoefirmly on the toe rest 148 and to release the arm 90 and permit it to beswung toward the heel end of the shoe in the manner above described. Thejack is then vswung forward manually to the position indicated in Fig.1, as usual in machines of the type illustrated. Upon the starting ofthe machine the jack is swung forwardly by its cam and the forepart andshank-leveling roll 20 is moved downwardly to engage the shoe in thewell-known manner characteristic of machines of this type. Downwardmovement of the heel end leveling roll 46, however, is delayed until theheel end portion of the shoe arrives substantially in position toreceive the pressure of the roll. The roll 46 is then forced downwardlyby the action of its cam 68, and is held in its lowered position underthe influence of the spring 84 until such time as in the reverseswinging movement of the jack the roll 20 is caused to return to the toeend of the shoe, whereupon the roll 46 is lifted by its cam to preventit from engaging the shoe for any substantial distance forwardly of theheel seat. It will be understood that in a cycle of operations such ashereinbefore described the roll 46 is thus. lifted twice in the cycle intime relation to the return of the roll 20 to the toe and is depressedtwice in time relation to the progress of the roll 20 from the toe endrearwardly. If the cycle includes, as hereinbefore described, aplurality of short reciprocations of the jack to cause the roll 20 tovoperate repeatedly along each side of the shank, the roll 46simultaneously operates repeatedly along the heel seat. Each time thatthe roll 46 operates rearwardly along the heel scat, its reduced endportions 106 engage the inclined faces 104 of the rollsupporting member102 and depress this member and itflsupporting bracket 100 to a ositiondetermined by engagement of the roll with the heel seat face of theshoe, the reduced portions of the roll entering the depressions 108 justbefore the shoe is in position to pass from under the roll. Each timethat the shoe is moved forwardly far enough to carry' its heel endbeyond the roll 46, the pawls 124 are moved into engagement with theratchet teeth 122 by the action of the roll-carrying bracket 52 on thearm 180, so that the roll support is locked against any substantialdownward movement from the position determined by the roll in engagementwith the heel 'seat` The roll is thus supported at such a height as toprevent it from drop Ding downwardly at the rear end of the shoe in suchmanner as to bend theedge of the sole and in position for the shoe' to.be moved under it again ywithout damage to the sole. Itl will be un-'supporting parts against the resistance of the spring plunger 94 whilethe shoe is moved forward to cause the roll 20 to operate along the'rear end` portion of the shank. In the reverse swinging movement of thejack'the shoe is returned toward the roll support until its rear endface engages the pad 96, and then the roll support 'is carriedrearwardly with the shoe simultaneously with the withdrawal of the pawls124 from eng-agement with the ratchet teeth, so that the roll 46 isagain permitted to apply its pressure to the heel end portion of thesole. Y

The invention is herein illustrated with reference to the application ofleveling pressure to a slice of the stitchdown type, but it is to beunderstood that it is not limited to use in operating on shoes of thatparticular type but is generally applicable to machines for levelingvarious kinds of shoes.
